Facebook共享链接中的自定义参数

Question

I am trying to share my custom link on facebook using this javascript function,

function postToFacebook(title, summary, image_url, U) 
 {
   window.open('http://www.facebook.com/dialog/feed?app_id= ' + fb_app_id + '&display=popup&caption=' + title  + '&description='+ summary + '&redirect_uri=' + encodeURIComponent('http://facebook.com') + '&link=' + encodeURI(U) + '&picture=' + image_url,'sharer','toolbar=0,status=0,width=548,height=325');
 }

In my "U" parameter I have this link => " http://localhost:4000/rings/solitaire-rings/lst?utf8=%E2%9C%93&min_price=&max_price=&name=solitaire-rings&category=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&metal_white=on&commit=APPLY "

and when user clicks on the link which is shared on facebook , user should get redirected to this link. forget about root url ie localhost:4000, because on production environment its considering required url.

the problem is that whne i am sharing this url on facebook user is getting redirected to " http://localhost:4000/rings/solitaire-rings/lst?utf8 ", and its not taking care of further parameters which are "%E2%9C%93&min_price=&max_price=&name=solitaire-rings&category=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&metal_white=on&commit=APPLY"

basicaaly I supposed to get this URL " http://admin.velvetcase.com/rings/lst?utf8=%E2%9C%93&min_price=&max_price=&name=rings&fashion_type=false&search=&gallery_order=&new_arrival=&best_seller=&search_material_id[]=Diamond&commit=APPLY " , but when I am sharing mu URL on facebook I am getting this one " http://admin.velvetcase.com/rings/lst?utf8=%E2%9C%93&amp%3Bmin_price&amp%3Bmax_price&amp%3Bname=rings&amp%3Bfashion_type=false&amp%3Bsearch&amp%3Bgallery_order&amp%3Bnew_arrival&amp%3Bbest_seller&amp%3Bsearch_material_id[0]=Diamond&amp%3Bcommit=APPLY " , which is not giving e required output.

Here is what I did successfully

var sharingUrl = "https://www.facebook.com/dialog/feed?app_id="+ facebookAppID +
                 "&link=" + sharingUrl +
                 "&name=" + encodeURIComponent(title) +
                 "&caption=" + encodeURIComponent(caption) +
                 "&description=" + encodeURIComponent(content) +
                 "&picture=" + encodeURIComponent(thumb) +
                 "&redirect_uri=https://www.facebook.com";
window.open(sharingUrl);

For all parameters we need to use encodeURIComponent , but I try to not use encodeURIComponent for sharingUrl , it still works!
